Brief Summary:
Two-part study to assess CTP-656 dosed as a solid oral dosage form versus Kalydeco and multiple-ascending doses of CTP-656 dosed for 7 days.

Condition or disease Intervention/treatment Phase
Healthy Drug: CTP-656 Drug: Placebo for CTP-656 Drug: Kalydeco Phase 1

Detailed Description:
This two-part study will assess in healthy male and female subjects a solid oral dose formulation of CTP-656 vs. Kalydeco® and the safety, tolerability and pharmacokinetic profiles of escalating CTP-656 solid oral doses following 7 days of dosing. In Part B, three doses of CTP-656 ranging from 75 mg up to 300 mg per day will be studied.
